I have an unexpected large capital gain this year. Which of course is a good problem, but I'd prefer to not have it - it will wash away my ACA subsidy and hit me two years hence with IRMAA. Are there some kind of (probably esoteric) investments in which one generates a loss immediately and recovers with gains over a period of time? Ideally, I'd be able to recognize as much as $100K in loss for 2022 and have the gains come in over at least a 3-5 year time period, if not longer. Thanks.
